Electronic Grade Phenolic Resin for Photoresist
Properties:
Phenolic resin for photoresist is an electronic grade high purity resin, with various metal impurities controlled to ppb levels, suitable for the production of various photoresist products. It is characterized by a strong reactivity of the molecular structure, which can prevent swelling in the photoresist development process, has strong resistance to plasma etching, high temperature resistance, good resolution, fast alkali dissolution rate and the ability to react with diazonaphthoquinone photosensitizer.
